ABSTRACT:
Each object on a panel has a respective location designated by an address and associated with an indicator lamp. A panel managing system comprises a memory for successively reading location address combinations. The indicator lamps are successively energized at the locations designated by the addresses read from one and the same combination so that a collector withdraws or inserts the objects at designated locations. The objects are detected to check the normal presence or absence of the objects in the panel after withdrawal or insertion of each object.
